You can use pass through shanks for beer entry through the back side of a cooler. Drill a 1" hole through the cooler, insert the shank, and use the two attached nuts to tighten up on the cooler. You will need nuts and nipples of the size line you are working with as well as hose clamps. We do not use pass through shanks in our boxes because we drill a hole that is same size as the line so we can pull it back in when we are traveling. However there might be instances where they would be appropriate. Pass through shanks can also be used to put through the side of a refrigerator to pass a gas line through.

Installation note: On a fridge there are generally no coolant lines running through the door but please check to see there are no lines connecting the door and the rest of the refrigerator. To test for coolant lines on a freezer start with a warm freezer then plug the unit in with the lid open. You should be able to see the lines form condensation on the inside of the freezer where there are lines running. Please still use caution when drilling.

BEST ANSWER:These Passthrough shanks are measured from end to end on the shank. Taking the hardware into consideration, the pass through would have to be about 3/4 shorter than the shank.Though the hose barb is permanently fixed, D1241 may be better suited for your application.

I bought this so I could move my CO2 outside of the spare fridge I use for my kegs. It could not have been easier; I drilled a hole and inserted the shank, then tightened it down. It even came with a white plastic washer which blends with the exterior of my fridge better than a black rubber seal. I bought two of the end piece sets (http://morebeer.com/products/14-tailpiece-hex-nut-gasket.html) and easily connect CO2.
